Application med-March 2o, 1922. yserial No. 545,394.

The invention relates to the manufacture of non-stretchable cords, particularly designed foil use in the forming of coat hangers and for similar purposes. It is the object of the invention to obtain a construction rwhich will not elongate under load Y and which will, nevertheless,rbe Vflexible and of a relatively large and substantially uniform cross section. l

In the manufacture of various iexible articles, such as insulated wire cords, etc.,-`

it is usual to use a braided covering. rIhis braid is generally7 formed of `yarn or cord woven Varoundthe vcenter core and, consequently, is not only laterally flexible, but

capable of a considerable degree of elongation. VVherethe core is metallic orV formedY to obtain a non-stretchable cord by the use of a braid formed of relatively non-stretch! able strands. Such a braid will therefore perform in vaddition to its' usual function of enclosing the core, the additional function of V,preventing elongation while at, the same time lateral flexibility is not interfered with. Y The invention therefore consists in the construction as hereinafter set forth.

In the drawings: K v Figure 1 is a sectional elevation of myv improved cord; y

Figure 2 is an enlarged cross-section thereof; f

Figures 3, 4, 5 and 6 lare enlarged cross sections showing modified constructions.

The core of my improvedv cord may be Vformed of any suitable vfilling material, preferably strands ofA a fibrous nature, such as "Y rope cotton, etc., as indicated at A. Surrounding this core there may 'be placed either spiral wrappings of fabric, as indicated at B, or any other material for build- `ing up the cross-section without interfering with flexibility. C is a braid surrounding the core A and wrappings B. This braid, instead of being formed of` strands of fibrous material, is woven from vmetallic strands, preferably forming a relatively open mesh. Such a fabric,if tightly woven anchoring to the metallic fabric.

In Figures 3 to 6 several modified construc- 7o C is formed of a plurality of wires which n .may be either stranded, braided or parallel.y i

about the core and wrappings, .will not elonf gate under stress, but will permit of lateral fiexing. To lincrease the diameter of the d cord additional wrappings such as D 'may be placed around the metallic woven fabric C and these in turn be enclosed in a covering E either woven` orformed in any suitable Inanner The .completed Vstructure will therefore-be flexible, of the desired ldiameter' and comparatively lnon-stretchable. Also,l hangersl ror fastenings'for the end ofthe cord may be securely attached theretotions are illustrated'. .In Figure 3 the core Surrounding the core is a ller C which is Vpreferably formed of jute or cotton; LSurrounding the filler.v is a body D of rubber:

compound-that ispreferably enclosed in ay cover D of some 'suitable material isuch as cotton7 woolen, plush, velvet or silk.V In Figure 4, I have' shown a core E that is surrounded by braids of cotton'Fl. while wires .F are braids of cotton Grenclosed by a ,suitablev fabric cover GH.' In Figure 5 I have shown a core I-I which may be eitherv wire or cord and which is enclosed within a' filler I-I of jute'orjcotton. vSurrounding the filler is4 a body I preferably f formed of braids of 'cotton which are en'- closed by a suitable fabric cover I. Embedded inthe body'I isa belt of `wires '-I which may be eitherinterwoven `with or between braids of the cotton.y In Figure 6, I have shown a core J preferably formed of stranded wire, a filler J of l'jute surrounding'the'cora a body K of braids ofy cotton surrounding the filler and enclosed withinga fabric, covering KC, Interwoven with or located between braids of the cotton forming the body'is a belt M of wires.v

What I claim as my invention is:

tightly braided' with an open mesh around and embedded in the vsurface of said filler for preventing elongation.

surrounding the cotton E are a plurality' of braided steel wires F. .Surroundingthe prrsingfa'- gore formed'of a. serisfofbrous strandsgarranged 1n a substantlally stralght 15 line, flexible stretchabl'e filler around Said# k@Orafor enlarging the 'cross sectom and Y A le'xlblerrwlpesiglandstgghtly 'braided with L relavely openv mesh around mid embedded n 'in-thesuiface of said filler foi preventing/20 Y elrigabtorll''of said C ord under lstress y and v "pmt-tinglateralflexing.' v i Y
